Currently I run a freedbsd zfs nas as well. I had planned to do something similar but I wanted to allow the places I store backups, some access to the storage. In your example, it would be your parents. I figured it would be a nice way of saying thanks. I was thinking syncthing or something. How do you do NATing?
All servers are behind a NAT, but the servers are only configured with SSH open. With the exception of the NAS I am using which also has NFS, iSCSI running. Also, only the backup servers are allowed to make connections to NAS I am using. The NAS I am using is not allowed to connect to the backup servers.
